This study aimed to compare the perceptions regarding professional competencies, pharmacy profession, and planned workplace between graduates with 5-year BPharm and 6-year PharmD and between those with PC and IP specialty. Methods: A cross-sectional national survey using a paper–pencil self-administered questionnaire was distributed to all new graduates attending the pharmacy licensure examination in March 2015. Results: Of all 1,937 questionnaires distributed, 1,744 were returned and completed (90% response rate). Pharmacy graduates rated highest on their competencies in professional ethics, followed by PC services and system management. They rated low confidence in medication selection procurement and pharmaceutical industry competencies. The 6-year PharmD graduates showed higher confidence in ethics and professional pride than the 5-year BPharm graduates. Graduates with PC specialty rated higher perceived competency in PC, system management, primary care, and consumer protection domains, while the IP graduates were superior in IP and medication selection and procurement domains, and most graduates (PC and IP) intended to work mainly in a hospital or a community pharmacy. Hospital was preferred for the PC graduates, and the IP graduates were more likely to work in pharmaceutical industry, regulation and consumer protection, sales and marketing, and academia. Conclusion: With some gaps still to be filled, the transition from 5-year BPharm to 6-year PharmD program with specialty tracks gave extra confidence to graduates in their specialty competencies and professional pride, leading to differences in preferred workplace. The findings of this study reflect that Thai pharmacy education continues to adjust to the needs of the society and the changing health care environments. Longitudinal monitoring to observe this transition is needed for both curriculum adjustment and competency of the graduates.

The auxin transport inhibitor response 3 (tir3) allele of BIG and auxin transport inhibitors affect the gibberellin status of Arabidopsis

The Arabidopsis gene BIG (formerly DOC1/TIR3/UMB1/ASA1) is known to encode a huge calossin-like protein that is required for polar auxin transport (PAT). Mutations at this locus, in addition to reducing PAT, can alter the sensitivity of plants to several hormones and light. The tir3-1 allele of BIG reduces the response of plants to application of the gibberellin (GA) precursors ent-kaurenoic acid and GA(12) and its semidwarf phenotype is partially reversed by C-19-GAs. The effects of auxin transport inhibitors (ATIs) on GA 20-oxidation was examined in wild-type and tir3-1 seedlings. 1-N-naphthylphthalamic acid (NPA) and triiodobenzoic acid lead to overexpression of the GA-biosynthetic gene AtGA20ox1 comparable in magnitude to the overexpression observed in seedlings treated with paclobutrazol, a GA biosynthesis inhibitor. In contrast to that of AtGA20ox1, overexpression of AtGA20ox2 is pronounced only in paclobutrazol-treated Col and Ler, and is less in tir3-1 and in all NPA-treated seedlings. Thus the effects of BIG and ATIs on the expression of genes encoding GA 20-oxidases are complex, and suggest that at least in some tissues ATIs, directly or indirectly, may reduce the level of bioactive GA and/or alter GA signal transduction

The housekeeping dipeptide permease is the Escherichia coli heme transporter and functions with two optional peptide binding proteins

Heme, a major iron source, is transported through the outer membrane of Gram-negative bacteria by specific heme/hemoprotein receptors and through the inner membrane by heme-specific, periplasmic, binding protein-dependent, ATP-binding cassette permeases. Escherichia coli K12 does not use exogenous heme, and no heme uptake genes have been identified. Nevertheless, a recombinant E. coli strain expressing just one foreign heme outer membrane receptor can use exogenous heme as an iron source. This result suggests either that heme might be able to cross the cytoplasmic membrane in the absence of specific carrier or that there is a functional inner membrane heme transporter. Here, we show that to use heme iron E. coli requires the dipeptide inner membrane ATP-binding cassette transporter (DppBCDF) and either of two periplasmic binding proteins: MppA, the l-alanyl-γ-d-glutamyl-meso-diaminopimelate binding protein, or DppA, the dipeptide binding protein. Thus, wild-type E. coli has a peptide/heme permease despite being unable to use exogenous heme. DppA, which shares sequence similarity with the Haemophilus influenzae heme-binding protein HbpA, and MppA are functional heme-binding proteins. Peptides compete with heme for binding both “in vitro” and “in vivo.
